Overview

What is he best known for?

The fields of study he is best known for:

Botany
Ecology
Shrub

Frank W. Ewers mainly focuses on Botany, Xylem, Water transport, Shrub and Chaparral. His Botany research integrates issues from Compressed air and Horticulture. His work carried out in the field of Compressed air brings together such families of science as Woody plant and Biomedical engineering.

The various areas that he examines in his Woody plant study include Crown and Habitat. His Xylem study frequently draws parallels with other fields, such as Liana. His studies examine the connections between Chaparral and genetics, as well as such issues in Rhamnaceae, with regards to Ceanothus megacarpus, Root system and Rhamnus.

His most cited work include:

The hydraulic architecture of trees and other woody plants (1133 citations)
Do xylem fibers affect vessel cavitation resistance (267 citations)
Relationships among xylem transport, biomechanics and storage in stems and roots of nine Rhamnaceae species of the California chaparral. (236 citations)

What are the main themes of his work throughout his whole career to date?

His primary areas of study are Botany, Xylem, Horticulture, Chaparral and Water transport. His research related to Shoot, Liana, Shrub, Woody plant and Ceanothus might be considered part of Botany. He works mostly in the field of Woody plant, limiting it down to concerns involving Hydraulic conductance and, occasionally, Biomedical engineering and Compressed air.

His biological study spans a wide range of topics, including Young's modulus, Phloem and Transpiration. Many of his research projects under Horticulture are closely connected to Air embolism and Embolism with Air embolism and Embolism, tying the diverse disciplines of science together. His Chaparral research includes elements of Rhamnaceae and Evergreen.

He most often published in these fields:

Botany (88.29%)
Xylem (68.47%)
Horticulture (18.92%)

What were the highlights of his more recent work (between 2005-2020)?

Botany (88.29%)
Xylem (68.47%)
Chaparral (18.92%)

In recent papers he was focusing on the following fields of study:

Frank W. Ewers mainly investigates Botany, Xylem, Chaparral, Shrub and Ecology. His research ties Irrigation and Botany together. Frank W. Ewers performs integrative Xylem and Water transport research in his work.

His Chaparral course of study focuses on Evergreen and Deciduous. He interconnects Arid, Dry season, Woody plant and Agronomy in the investigation of issues within Shrub. While the research belongs to areas of Ecology, he spends his time largely on the problem of Stomatal conductance, intersecting his research to questions surrounding Plant ecology, Juniper, Agave, Deserts and xeric shrublands and Canopy.

Between 2005 and 2020, his most popular works were:

Relationships among xylem transport, biomechanics and storage in stems and roots of nine Rhamnaceae species of the California chaparral. (236 citations)
CAVITATION RESISTANCE AMONG 26 CHAPARRAL SPECIES OF SOUTHERN CALIFORNIA (191 citations)
Xylem density, biomechanics and anatomical traits correlate with water stress in 17 evergreen shrub species of the Mediterranean‐type climate region of South Africa (131 citations)
